Drew T 03794d91cd feat(phase-30 S43): make audit-disc — the disc PARTITION holds at residue 0; 34 UNCLAIMED code payloads 
L1 of Drew's definitive disc audit ("we really need a full audit that definitively lists ALL code
that we need to decomp"). THE INVARIANT (R32): every byte on the disc belongs to exactly ONE bucket,
the buckets SUM TO THE DISC, and residue is a DEFECT — a partition with an asserted residue of zero
is a completeness proof; a longer list is only a longer list.

- WALKS THE DISC IMAGE, NOT OUR CONFIGS, classifies WHOLE payloads (no window), and decodes BOTH the
  raw and LZSS layers — the three shapes that produced the three "more code all along" surprises
  (the 0.4.dec glob missing 4 SC07 overlays; disc_code_sweep blind to COMPRESSED code, its type-4
  row vacuous for 138 known binaries; a 4,096-word window reading only payload heads).
- CLAIMED-BY IS DERIVED (R33): config/check.<bin>.sha IS the SHA1 of that binary's disc payload, so
  payload->binary is a hash lookup against the build's own byte-identity gate. It cannot drift.
- RESULT, 416,021,760 bytes, 1,291 payloads, RESIDUE 0:
    onboarded-code 32,564,876 (7.83%) · UNCLAIMED-CODE 1,700,049 (0.41%) ·
    classified-data 150,631,480 · audio-video 184,338,000 · filesystem-metadata 46,787,355
  34 UNCLAIMED code payloads — largest a 383,783 B type-1 in MAIN.CD, the rest small type-1 entries.
  These are the "there was more code all along" surprises, now ENUMERATED instead of stumbled into.
- MY OWN FIRST RUN FAILED THE PARTITION by -49,709,520 B, and the fail-closed exit is what caught it:
  .DA entries' LBAs point PAST track 1 into the CD-DA tracks (double-counted against the whole-track
  audio total), and .STR/.XA are MODE2 FORM2 (2324 user bytes/sector, not 2048). Both fixed.
- NOT wired into tools-health: it needs disks/, which a fresh clone does not have (H1).
- KNOWN GAP, stated not hidden: LIST.CD fails the TOC walk (it IS the TOC cache, not a container)
  and is booked as data — correct today, worth a real classifier when L2 lands.

Disc ledger — the completeness partition (L1)

tools/disc_audit.py (make audit-disc). Walks the DISC IMAGE, not our configs; classifies WHOLE payloads (no window) at BOTH the raw and LZSS-decompressed layer. claimed-by is derived from config/check.<bin>.sha — the build's own byte-identity gate (R33). Residue is a DEFECT (R32), not a rounding note.
